The sudden attack of three Level 19 Puppet Dragons successfully killed a Level 19 Titan and took the Titan's heart.
Thus, the direction of this world started veering off in a different path.
Initially, the Thunder Research Institute, which lost its Level 19 guardian, began researching ways to remedy the situation.
Later, other forces noticed this development and, to prevent the Thunder Research Institute from regaining its foothold, they also quickly started their research.
Among them, Dragon Exile Tower and Silverlight Academy were the first to research the use of the Titan heart to make Puppet Dragons, and they quickly restored some items.
However, the most crucial part of letting Puppet Dragons grow to Level 19 had still not been figured out.
At this time, news came from the Dark Academy, which had always been situated in the Underworld.
This included the hero's growth path.
